INK FOUNTAIN FOR PRINTING MACHINES.

. Application filed August 1, 1923.

This invention relates to a fountain for ink and the principal objectsthereof are to provide a new and improved construction of the same inwhich the machining of the contacting; parts will. be avoided and theycan be assembled by an unskilled mechanic and yet will. fit accuratelyand operate effectively without shortening; the life of the machine.

More specifically, the invention involves new and improved means formounting the fountain roll in permanent bearings and aback and scraperblade also, and means whereby the fountain itself can be mou'nted on theframe in accordance with the same principles without machining theparts.

" ."tdditional objects and advantages of the invention will appearhereinafter.

Reference is to be had to the accompanying: (llilWlIlQQS, in which Fig.1 a plan of an ink fountain with certain parts removed to show theconstruction. the same being made in accordance with this i invention;

Fig. 2 is a front elevation of the same;

'Fig'. 5 is a fragmentary plan of one end of the fountain back:

hi (i is a plan of the bracket carrying the hearing for the end of thefountain roll shaft; and

Fig.1. 7 is a sectional view of the back.

Tt is to be understood that this fountain is to be mounted on a printingmachine frame 10 to be used for the usual purposes in the usual way.Only a fragment of the cast iron frame of the press is shown as theinvention is independent of the rest of the printing machine. This frameis provided with a preferably horizontal surface 11 on which. thefountain is to be supported the support for one. end of the fountainonly being Sl'lOWll in the drawings. It is to be understood that theother end is supported in some way. Heretofore it has been necessary tomachine this toprovide a true surface for the fountain to rest on andthe under side of the fountain was machined at the same point for thesame purpose. According to this invention. this machining is avoided.When this machine frame 10 is cast, instead of being provided withexcessive metal on the surface ESerial No. 655,770.

11 designed to be planed off to provide a true seat for the fountain, itis provided with an undercut recess 12 at that point and contains lessmetal in the original casting than is required forthe supportofthefountain in the proper plane. This saves some cast'iron.

After the machine frame is cast a metal mold or die. not shown. isplaced over or adjacent to the surface 11. It is so shaped that a bodyof soft metal 13 can be cast in the mold and in the undercut recess 12so that it will be held'in the undercut recess permanently and willproject above it. This mold has a flat, or at least a regular surfaceagainst which the metal is castand which provides a flat top for thismetal accurately finished in thecasting operation to constitute asupporting seat. This is accomplished by employing for the metal 13 a.non-shrinking and non-expanding metal or alloy such for example asantimonial lead, an alloy of lead and antimony that neither contractsnor expands materially on solidifying from a molten state. It can becast at a lowtemperature of 500 to 600? 11. It solidifies quickly andhas sufficient strength and hardness to sustain the weight and pressureto which it is subjected in this machine. This flat body of metal 13thus constitutes a supporting seat for one end of the ink fountain. Aseatcrtactly like it is furnished on the other side of the frame for theother end. This is accon'iplished without any machining operations. thefinishing of the surfaces being done entirelyby casting. i

Thefountain box 15 is provided with two arms 16 exactly opposite eachother and projecting: outwardly therefrom. In the castof this fountainbox 15 from iron an undercut recess 18 similar to the recess 12 isformed. After the casting is produced a metal mold is placed over thisundercut recess and so shaped that the same alloy can be cast in thisrecess and form a projecting seat 17 having a flat surface fitting thesurface of the seat 13. These are cast to the same size and havingpreferably flat surfaces fitting; each other. But if desired thesesurfaces can be made of some other shape so long; as they fitaccurately. In the assembling of the parts the fountain box 15 is placedin position with its two seats 17 restinc; on the seats 13. Then theseparts can be bolted together by inserting bolts through holes 19 left inthe process of casting to pre vent all relative motion. This furnishes:an accurate way of providing for mounting the fountain box on the framein a predetermined position and securing accuracy in the placing thereofwithout -1nach-ining the frame or the fountain box. Of course the moldsor dies used have to be machined accurately but they are used over andover.

The fountain box 15, as cast-is provided in its end. wall 23 with twoconcave recesses opposite :each other, each one "having considerablewidth and each provided with an undercut recess 20. I have shown theserecesses or seats as of arcuate form, almost a semi-circle. They arearranged symmetrically with respect to each other, one directly.

opposite the other. After the iron casting constituting the main body ofthe ink fountain box 15 is cast and cooled. a metal mold is placed overeach of these recesses in such a way asto provide a space adjacentthereto. The inner surface of this mold is of finished metal. An alloysuch as above described is then cast in each of these molds. It formstwo concave supporting-seats 22 of the alloy finished on their concavesurfaces in thecastin; process and not requiring any further finishing.The edges also are "finished flatby the walls of the'mold in which theyare cast.

Inow cast a pair of fountain roll brackets 25 having a general shapesimilar to the interior of the two seats 22 but of smaller radius andformed of cast iron. These are provided with undercut recesses 26 andcoated with the alloy described above to form a seating surface 27allaround the conveX lower porti on ofthe bradket. At the same time orsubsequently a flat seat 28 of the same alloy is provided on the topedge of each bracket near one end. The exterior curved surface of thesoft metal .27 is formed to fit exactly the concave surface of one ofthe seats 22 so that these brackets can be put into the seats 22 and theparts can be united by bolts 29 and held firmly in position in thatmanner. In this way these brackets 25 are fitted in position on the endsof the ink fountain without resorting: to machining methods at all andyet they are accurately fitted and seated in position and firmly held. Ialso provide a flat coating 34 on one "side formed vof the same softmetal .andhaving a flat outer bearing); surface for engaging the flatend of the fountain roll I also provide each of the brackets 25 with anopening '30 .therethrough and T line this opening with a lining of softmetal 31 in the sa'me'manner as above described by casting 'it into theopening and securing-an inner surface of exactly cylindrical. shape bymeans of a hard metal core employed in the casting operation. Thesefurnish bearings for the shaft 32 of the fountain roll 33 and permit ofthe mounting of the fountain roll in these brackets and bearing g s sothat it is permanently and accurately held in position although it is tobe understood that the bolts 29 can be loosened and the fountain rollwith IES shaft and the two brackets 25 removed.

The bodiesof soft metal 27' and 34 are shown as cast integral with eachother at one casting ope iation.

On each of the arms 16, above mentioned,

beyond the seat 1 I provide a projection 35 and form upon it a fiatsupporting seat 36 of the same alloy and in the same manner as describedin connection with the formation of the seat 13. I also provide abearing 37 having an accurately cast soft metal lining 38 for the shaft32 with a projection 39 having a soft metal seat- 40 formed on it in thesame way as the seat 17 above described and fitting; the supporting seat'36. This is mounted in position on this seat so as to give a propersupport to the bearing bracket 37. @no of these is mounted on each endof the machine in this manner near the ends of the shaft which is alsosupported by the bearings 3-1ncar the ends of the fountain roll.

The parts so far described constitute means for accurately supportingthe fountain itself on the frame of the printing machine and foraccurately mounting and supporting the fountain roll in the fountain soas to be capable of rotating on. its own axis in the usual way. Allthese results are accomplished without machining either the frame of theprinting machine or the fountain itself. It will be understood that thefountain roll and its shaft may be machined accurately in the usual wayorotherwisc constructed so as to have smooth surfaces, those of theshaft fitting in the bearings 31 and 3-8. In this way the parts ca beassembled without resorting to machining methods or without requiringhighly skilled labor for connectin g them.

"In the assembling of the parts so 'described the fountain roll with itsshaft 32 is provided with two fountain roll brackets lav placing them onover the ends of the shaft so that the shaft passes "throughtheperforations 30 and has its hearings in the soft metal linings 31. Thesefountain roll brackets are moved along; the shaft up against thefountain roll so that the seating body of soft metal 34; on eachcontacts with the tlat'end of the roll if desired. or it can be spacedtherefrom. Then these brackets 25 are set down into the seats 22. Thusthe seating bodies of metal 27 register with the seats 22 and the bolts'29 are inserted and fastened up. This firmly and accurately mounts theroll in position on the box.

The two brackets 37 are mounted on the ends of thesha'ft 32 so that thelatter has its "hearings in the linings 38. Then these brackets 37 arebrought inwardly or outwardly as necessary and turned to the properangle so that the seats 40 rest on the seats till 36 and any properfastening bolts or the like are inserted as in the usual cases to holdthem in position. Thus there are four bearings for the shaft 32 at widedistances apart to hold it and prevent vibration.

The assembled fountain box 15 is 110w located in position on theprinting press frame 10 with the seats 17 in contact with the seats 13and in registration therewith, and bolts or other fastening devicesplaced in the perforations 19. This firmly secures the fountain box tothe frame.

It will be seen that these parts are assembled easily and rapidly. andwithout the use of skilled labor, and that no finishing of any of theparts is required except the fountain roll shaft, and in some cases thefountain roll itself.

I also carry out similar principles in the mounting of the scraper bladeand the back on which it is carried. For this purpose the fountain box15 is provided with two integral bosses 42 at opposite ends and near oneside. In the casting of the fountain box 15 these bosses are providedwith a central cylindrical passage 41 and'an undercut recess 45 on theinside surface@ This undercut recess is filled and a projecting bearingseat 46 formed and the passage 41 lined with the same soft metal at 44in accordance with the process above described. This can be done in oneoperation having the lining or hearing 4-4 and seat 46 integral.

Now. the fountain back 47 is formed of cast iron and provided with apair of opposite arms 4-8 each having a deep recess 49 as cast. Thisrecess is lined with this soft metal to form a cylindrical bearing 50and provided with a projecting flat circular hearing seat 51 of the softmetal preferably integral therewith. These two seats at the oppositeends of the back are formed in alignment by properly locating the moldsin which they are cast. Obviously each has a sn'iooth inner bearing 50of cylindrical shape and a flat circular seating surface on the outside.The diameter of this hearing surface 50 the same as the diameter of thelinings of the two perforations 44. The circular flat bearing surfaces46 and 51 are of equal extent and fit each other accurately; Also on thefountain back is located an integral arm 52 at each end. These arms areprovided with two seats 53 of soft metal 'of the same size and shape asthe two seats tively. These pins constitute pivots on which the fountainback can swing and the seats 28 constitute supporting seats for the backto hold it in place.

On the back 47 at a distance from its front is placed a flat seat 55 ofsoft alloy or metal as above described and against .it by means of a bar56 and screws 57 is secured a scraping blade 58. This also thereforeheld in position without the necessity of machining the parts of theback 47. In the back 47 at two or more places along its forward edge arecast inclined perforations 60 and at the bottom of the same are castbodies of soft metal 61 about a master screw, not shown, so that thesebodies of metal are provided with an internal screw thread when themaster screw is removed. Then adjusting screws 62 are threaded intothese threaded bearings 61. These screws 62 rest on top of the scraperblade 58 and adjust it toward the surface of the fountain roll.

In this way a large amount of the ordinary machining expense,substantially all of it. is eliminated and yet all the advantages ofhaving accurately planed and turned surfaces are secured and there iseven less danger of any inaccuracy or of a part of a machine beingthrown away on account of some error in the machining.
